FS-Curtis RNB100 Non-Cycling Refrigerated Dryer 100 SCFM #FRNB00100-1XA5XX

FS-Curtis RNB100 — 100 SCFM Refrigerated Air Dryer

A commercial shop running several bays off one central compressor needs dew point control that doesn't waver when demand spikes — the RNB100 is sized for that kind of steady, higher-volume commercial use.

That's what the FS-Curtis RNB100 solves — a 100 SCFM non-cycling refrigerated dryer, a dependable way to keep the air line dry without adding a piece of equipment that needs its own babysitting. It's also available with a factory-matched Filter Package (prefilter CF7-24-8-DGL + afterfilter CF5-24-8-DGL) as an add-on option, which puts factory-correct filtration inline from day one, instead of adding it as an afterthought once a moisture problem shows up.

Who the RNB100 Is Built For

• ✅ A multi-bay shop running a mid-size rotary screw compressor (typically 15-30 HP) where several techs pull air from the same line throughout the day
• ✅ A shop that already has 3-phase power in place and wants a dryer sized to actually match the compressor's real output, instead of undersizing and choking the system
• ✅ An operation that needs consistent dew point control across a full 8-10 hour shift, not just intermittent weekend-warrior use
• ✅ A shop that's grown out of a smaller single-phase dryer and is tired of it cycling or falling behind once two or three bays are running air tools simultaneously
• ✅ A facility running sensitive downstream equipment — spray booths, sandblast cabinets, precision pneumatic tools — where wet air causes real, expensive problems

What the RNB100 Is NOT Built For

• ❌ Small single-bay shops with light, intermittent air demand — a smaller RNB model in the 115V tier saves real upfront cost
• ❌ Very high-volume industrial operations that exceed this unit's rated SCFM — check the 200+ SCFM models instead so the dryer isn't the bottleneck

What Makes the RNB100 Different

Heat Exchanger

The RNB100 uses a stainless steel brazed plate heat exchanger, engineered for reliable, consistent dew point control at 100 SCFM without fouling or excess pressure drop.

Condensate Drain

Timed electric drain removes collected moisture automatically — it discharges on its own schedule, freeing your team from tracking one more manual step.

Refrigerant & Air Quality

Uses R513A refrigerant, a low global-warming-potential option, and delivers ISO 8573-1:2010 Class 4–5 pressure dew point — dry, reliable air for general shop and industrial use.

Optional Filter Package

Choose the “Includes Filter Package” option to add a factory-matched prefilter (CF7-24-8-DGL) and afterfilter (CF5-24-8-DGL), sized to this dryer's flow rate and ready to plumb — one less step for your install crew.
